Predicting turnout for the EU referendum is harder than previous elections, a Welsh political expert has said.

Professor Roger Scully from the Wales Governance Centre said it could be anything between 55% and 70%.

"This is such a hard poll to call on turnout. Looking at polling evidence and interest in the TV debates, I suspect it could be mid to low 60s".

Her added: "I think that a low turn out could benefit those who want the UK to leave the EU. The leave supporters are passionate and will vote. A higher turnout could benefit the remain camp as you could get more younger voters and people who are OK with the status quo coming out".
